Fedora Servers :: Dhcpd Option Depending On Manufacturer?

I would like to send a specific option 15, domain-name, to a few clients on a network from a specific manufacturer. Usually all clients [URL] from the DHCP server, but when a client with mac address bellonging to manufaturer A asks for an IP address I would like to give them [URL] How would I go about doing this? Feels like it should be possible but I am not sure how.. I remember doing something similar in a microsoft DHCP server using vendor-identifier and passing out a vendow-specific option.

class "xxx" {
match if substring (hardware, 1, 3) = 00:00:10;
option domain-name "yes.this.works.com";
}
